The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the pipe for this stretch of coast.
Right off the bat, the wait is on. There’s nothing really worth paddling out for in the next few days. The initial surf that shows up on Monday 31 August is a no-go; that 6ft NW swell is blown out by a cross-on wind and the energy is just okay at (738). We’ll be sitting on the beach for that one.
We get a brief flash of hope on Tuesday 1 September. The morning session is the real standout here. That 5ft NW swell hits with glassy conditions—dead calm, no wind. That is about as clean as it gets. The water is much warmer than usual for this time of year, sitting at 75°, about 5° above normal. It’s a noticeable change. That window is your best bet in the first week, but it's short-lived as the afternoon turns sloppy.
After that, the forecast goes flat and quiet for a solid stretch. From Wednesday 2 September right through to Friday 4 September, wave heights barely crawl above 2ft, and the period is short. Just not enough push to get a decent ride. You’re looking at a gap of a few days with next to nothing.
Things start to stir again by Saturday 5 September. Saturday morning shows a pulse of long-period groundswell at 5ft NW with a period of 15 seconds. That’s a very long period, which means plenty of energy (443) and nice shape, but at a beach break it can sometimes bowl too straight. Still, with glassy conditions, it’s a solid session. The afternoon jumps to 5ft but the wind turns onshore, so stick to the morning.
Sunday 6 September morning is another one to mark down. You’ve got a clean 5ft NW swell with a 12-second period and light cross-offshore wind. That’s good quality, and the energy is moderate at (551). This is probably the best shaped, most consistent option in the first weekend.
The middle of the following week has a few small windows. Tuesday 8 September morning is only 3ft, but that 12-second period gives it a little more life. It’s glassy and surfable—nothing epic, but you’ll get a few.
Now, looking ahead, there are two mornings that stand out as the best of the whole outlook. Thursday 10 September morning brings a clean 5ft NW swell with calm, glassy wind. That is a prime session. The energy sits at (384). It’s the same on Friday 11 September morning: another 5ft NW, totally flat, dead calm. Perfect clean conditions for that stretch.
The last real highlight is further out. On Tuesday 15 September morning, a solid 5ft NW swell arrives with a long 12-second period and glass. Energy jumps to a strong (827). This one is marked as very good quality. It’s the kind of session you book a late start for. The afternoon bump up to 6ft with a cross wind makes the afternoon less ideal, but that morning window is the pick of the second week.
So to sum it up: your standout windows are Tuesday 1 September morning, Saturday 5 September morning, Sunday 6 September morning, and the Thursday 10 and Friday 11 September mornings. Further out, Tuesday 15 September morning looks like a cracker. Just remember, the longer-range stuff is promising but we’ll have to see how it shapes up as we get closer.
Stay stoked,
Rusty

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
